To all whom it may concern:

Be it known that l, WALTER W. LIND, a citizen of the United States, anda resident of East Orange, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in Sad-Irons,of which the following is a specification.

The invention relates to improvement-s in sad-irons of the so-calledself-heating class, and it consists in the novel features andcombinations of parts hereinafter described, and particularly pointedout in the claims.

r1`he iron of my invention comprises a lower part which is hollow anddesigned to contain a suitable fuel for keeping the iron hot, and anupper part carrying the handle and adapted to be placed downwardly uponand be detachably secured to said lower part.

The object of my invention is generally to increase the value,efliciency and convenience in use of sad-irons of the class to which myinvention pertains.

One purpose of my invention is to provide a structure affording animproved combustion chamber so that the iron may be properly heated, andanother purpose of the invention is to enable the convenient cleaningoutof said chamber whenever desired.

A further purpose of the invention is to provide means for detachablysecuring the upper part of the iron to the lower part thereof in variousadjustments so as to regulate the drafts through the combustion chamber.

Another object of the invention is to provide an adequate body of metal,without undue weight, in the bottom of the iron so that the iron may notwith undue rapidity be come cooled on its ironing face, especially whileironing damp fabrics.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being' had to the accompanyingdrawings, in which:

Figure 1 is a top view of the lower portion or section of the iron of myinvention; Fig. 2 is a central vertical longitudinal section of thecomplete iron; Fig. 3 is a central vertical transverse section of thesame on the dotted line 3--3 of Fig. 2; Fig. 4 is a detached top view ofthe mechanism carried by the top section of the iron for securing it tothe lower section thereof; Fig. 5 is a top view of Speeication ofLetters Patent.

the complete iron, and Fig. 6 is a detached sectional view through aportion of the top section of the iron on the dotted line 6-6 of Fig. 5.

In the drawings 10 designates the lower section of the iron, 11 the topsection thereof, and 12 the handle connected with said top section bysuitable standards 13. The top section 11 comprises a top-plate 14, adownwardly encompassing edge-flange 15, and outlet flues 16 provided atopposite sides of the front and rear ends of said top section and formedby upwardly and outwardly curved portions 17 of said top-plate 14 eX-tending above the adjacent portions of the flange 15 and leavingopenings above said flange to constitute said flues, as indicated in Fig. 6. The top-section 11 carries the means for connecting it with thelower section 10, and these means comprise two suitably spaced-aparttransverse bars 18 pivotally mounted, on end trunnions 19, in the sidesof the flange 15, arms 20 extending downwardly from said bars 18 andhaving oppositely extending dogs 21 at their lower ends, a longitudinalbar 22 below the bars 18 and having in openings in its ends transverserods 28, inclined lingers 24textending downwardly and outwardly from thebars 18 and below the rods 28 (Fig. 2), and a central pivot-pin 25connected with the bar 22 and having at its upper end a button 2Gpreferably provided with a hinged loop-handle 27.

rEhe top 14 of the upper iron-section 11 is provided with a longitudinalslot 28 adapted to receive the button 2G, which when it is in line withsaid slot may be depressed into or pulled upwardly through the same.'Vhen the button 2G is pressed downwardly into the slot 2S, it depressesthe bar 22 and rods against the fingers 24 and thereby compelling thebars 1S and arms 20 to rock downwardly and inwardly toward each other,with the result of releasing the dogs 21 from the lower section 10 ofthe iron and leaving the upper section 11 free to be lifted from saidsection 10 or adjusted upwardly or downwardly thereon. W'hen the button26 is pulled upwardly through the slot 28 it elevates the bar 22 againstthe bars 18 and causes said bars and their arms 20 to rock outwardlyfrom each other, with the result that the dogs 21 are forced intoengagement "Jv Zvi.

23, causing said rods to press downwardlyi with the lower iron-section10, for connecting the upper and lower sections of the iron together.After the button 2G has been pulled upwardly through the slot 23 forconnecting together the upper and lower sections of the iron, saidbutton is given a one-quarter turn to cross the slot 2S and lock thedogs. 21 in their engaging relation to the lower iron-section 10. rihebutton 2G is provided with a pivoted loop 27 for convenience inmanipulating it, and said loop is pivotally connected with the button 2Gso that when the button is across the slot 23 the loop may be foldeddownwardly out of the way of the hand of the person using the iron. Thearms 20 are thus rocked toward each other to release the upper section11 from the lower section 10, and they are rocked from each other toconnect said sections together, and as shown in Figs. 3 and a there aretwo arms 21 at each side of the iron.

The lower section 10 of the iron is a hollow shell comprising a bottom28, vertical sides 29 and interior frame 30, and the top section 11covers the section 10 and its sides 15 pass downwardly7 over the sides29 of the section 10. The sides 29 of the lower section 10 are recessedor cut away at opposite sides of the section, as at 31, to receive thedownwardly extending arms 20, and at the opposite edges of the recesses31 the sides 29 are formed with a series of serrations or teeth 32 tointerlock with the` dogs 21 of said arms. Vhen the top section 11 isapplied to the lower section 10, the dogs 21 will be interlocled withsuch of the teeth 32 as will leave the top section in the desiredrelation to the lower section, the series of teeth 32 aording a means ofadjustment enabling the top section to be elevated or lowered inaccordance with the amount of air-draft to be permitted through theinterior combustion chamber of the iron. The lower section 10 is notonly recessed at its opposite sides, as at 31, but is also recessed atboth ends, as at 33, and these recesses 31, 33 are located at a suitableelevation above the bottom ofthe section 10 and afford draft spaces forthe air required for combustion, which spaces may be varied in size bythe vertical adjustment of the upper section 11 on the lower section 10,the flange or skirt 15 of the top section 11 serving to more or lesscover the recesses 31, 33 as said section is adjusted upwardly ordownwardly.

The bottom 23 of the lower cast section 10 is formed on its uppersurface with a series of vertical somewhat cone-shaped studs 34 whichare distributed over and integral with said surface. The studs 34 arebeneficial in several respects, one being that the fuel is placed uponthem and that they allow the air to find its way below the fuel. Thestuds 34 are also of advantage because they hold the heat and preventthe bottom 28 from cooling with undue rapidity, thus allowing the ironto be constantly used a greater length of time. Self-heating irons,espe-I cially when used on damp clothes, give off their heat with somerapidity, the bottom of the iron being comparatively thin. rIhe studs 34not only serre to support the fuel and aid in securing proper combustionbut afford an increased body of meta-l in the bottom of the iron withoutcreating undue weight in the same or unduly reducing the capacity of thefuel chamber. The shell 30 extends entirely around the inner walls ofthe lower section 10, as shown in Figs. 1 and 2, and at its oppositesides, adjacent to the recesses 31 in the sides of said section 10, thebody of the shell inclines downwardly and inwardly, forming shields 35which while preventing the spilling` of the fuel through said recessesdo not obstruct the air draft through the same, as may be seen byreference to Fig. 3. The lower edges of the shields 35 are formed with aseries of recesses 36, which form draft passages. The sides of the shell30, at the front and rear of the shields 35 are cut away, as at 37, andthe front and rear ends of the shell are formed with draft passages 3S.rlhe shell 30 may be made of sheet metal and sprung into the lowersection 10 or it may be riveted to said section or left free to bereadily lifted therefrom. The shell 30 guards trie recesses 31, 33without obstructing the drafts through the same and by being cut-away orrecessed at 37 avoids occupying undue space in the combustion chamber ofthe iron.

ln the employment of the iron the top section 11 is removed and the fuelplaced in the bottom section 10, as usual, and in restoring the topsection to the section 10, said top-section will be adjusted downwardlyto the extent desired but leaving the lower portions of the siderecesses 31 and end recesses 33 uncovered for the passage of air throughthe same. The draft passages at 31 and 33 may at any time be varied byadjust-ing the top-section l1 vertically with relation to the lowersection 10, so as to modify the draft through the combustion chamber asthe conditions therein might require. The draft outlet from thecombustion chamber is through the flues 16. The recesses 31, 33 atopposite sides and ends of the iron not only provide for the adequateadmission of the air but enable the ash to be blown, from time to timeas may be dcsirable, from the combustion chamber. y
